Oil fume filtering device, and range hood with filtering device

Abstract

The invention discloses an oil fume filtering device. The oil fume filtering device comprises a filtering mechanism, the filtering mechanism has a first side and a second side which are opposite, thefiltering mechanism comprises at least two net plates which are arranged at intervals side by side in a direction of a connecting line of the first side and the second side, and a space between the two adjacent net plates form a channel for oil fume to go through. The invention also discloses a range hood using the oil fume filtering device. The arrangement of the lamellar net plate shape filtering mechanism makes the contact area of oil fume and the filtering mechanism large, so the oil separation degree is improved, and the oil fume purifying capability is improved; and the arrangement of adriving mechanism and a transmission mechanism makes the net plates extruded in order to extrude oil on the net plates into a flowing liquid, so the self-cleaning of the filtering device is realized.

Description

technical field [0001] The invention relates to a kitchen appliance, in particular to an oil fume filtering device and a range hood using the oil fume filtering device. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and health, people pay more and more attention to the environmental protection indicators of range hoods. The range hood has an important performance index - grease separation. The stronger the ability of the range hood to filter the oil in the oil fume, the higher the separation degree of oil. [0003] At present, traditional range hoods generally use porous filter screens to intercept oil fume, and filter the oil fumes of the range hood by colliding with the oil fume gas to decelerate and condense. For example, the Chinese patent application number 201420296349.X discloses a rotary grease separation filter for range hoods. The center hole of the filter disc is installed on the rotating shaft of ...

AI Technical Summary

Problems solved by technology

However, the manufacturing process of this kind of filter screen structure is very complicated, and the winding of the steel wire can only be in a straight line between two fulcrums, similar to the staggered structure of straight spokes of bicycle tires, which affects the filtering capacity on the one hand, and on the other hand , the dense steel wires rotate to produce a lot of noise, and the sound quality is degraded

[0005] In addition, neither the porous filter screen nor the rotating net disk has self-cleaning function, so it is very troublesome to clean after long-term use
